I recently changed my 1995 BMW 328 for a NSX 1993 manual car (prior to power steering and 16/17 inch wheels). Although the straight line speed is fantastic, I feel very nervous about the cars steering/handling. The steeering seems reluctant to turn sharply and through a fast bend the car seems nervous and twitchy! The BMW on the contrary felt far more secure and sure-footed through corners, without any movement through the corner. Has anyone any ideas as to what could be the problem, as I doubt that this is the handling that has earned the NSX such praise. PS my car rides on 15/16 wheels with 225/50 rear tyres.
